DRAFT-EQUALIZER.

Specification of Letters Patent.

Patented Feb. 1, 191.0.

To all whom it may concern:

Be it known that we, \VJLIJAM Enriio'r'r and Bonner H. Soi-inaoirrnn,citizens of the United vE-ltates, residing at Beatrice, in the county ofGage and State of Nebraska, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is z specification.

()ur invention relates to draft-equalizers for wheel cultivators orother wheeled agricultural implements, or vehicles, and especially todevices for equalizing the draft of four horses, two on each side of theimplement.

Another object of our construction is to overcome the downward strain,or neckweight, usually produced on the necks of the horses by thepressure of the tongue, due to the fact that the forward ends of theplow-beams are usually attached, in implements of this class, eitherdirctly or indirectly, to the tongues in front of the axle of themachine. We counteract this neckweight by providing for the applicationof the traction power at points in the machine as low down as iscompatible with its proper operation.

lVe also employ in this implement rotatable draw-bars mounted to rotatein bearings attached to the frame, to which bars the traction is appliedin such a manner thatthe equalization is effected by the rotation ofsaid draw-bars.

In the foregoing particulars our present invention is practicallyidentical with the construction shown in an application filed by us June21, 1909, and bearing Serial Number 503,506. The special peculiarity ofour present invention is the employment, in connection with therotatable draw-bars, of flexibly mounted equalizing-bars, located eitherbelow or above said rotating bars, the traction power being appliedfirst to said equalizing-bars, and being thence transmit ted, bysuitable connections to the rotating draw-bars, as hereinafterdescribed.

In the accompanying drawings Figure l is a perspective View of a portionof a cultivator provided with our improvements, parts not immediatelyinvolved being omitted. Fig. 2 shows a modification of the con structionshown in Fig. 1, the equalizing-bar being located abovethe rotating bar,instead of below it. Fig. 3 is a vertical section through the rotatingdraw -bar and the equalizing-bar, on the line 33 of Fig. 1. lfiig. 1- isan end elevation of said draw-bar, equalizingbar, and a (flraft-bar.

1 indicates the main sill or axle of the implement, to the ends of whichare pivoted the crank axles 2.

3 and d are members of the main frame.

5 indicates the poles or tongues projecting forward from the frame,rigidly secured thereto, and practically forming a part thereof. ()11the tongues are secured sleeves (i, which form bearings for one end ofthe rotatable draw-bars 7. The other bearings for said draw-bars are theloose sleeves 8,1igidly secured to the diagonal bars 9, extending fromthe tongue 5, and supported by the frame. The draw-bars 7 carry, on eachside of the bearings 8, loose sleeves 10, to

which are rigidly attached depending draftbars 11, connected at theirlower ends to swingletrees 12'. Extending between said draft-bars 11,and flexibly connected thereto, are horizontal equalizing-bars 13. Saidbars are pivoted centrally to bolts let, set in brackets 15, whichbrackets are rigidly cured to draw-bars 7, so that traction applied tosaid equalizing-bars 13 will rotate draw-bars 7. The equalizing-bars 18are flexibly connected to the draft-bars 11 in any preferred manner. Wehave shown a suitable connection in Fig. t, in which eyebolts 16 passthrough the equalizer-bars and e11- gage links 17 carried by thedraft-bars 11.

The inner ends of the rotating draw-bars 7 carry extending radial arms18, to the outer ends of which is connected a chain 19, which passesacross the machine, guided by the sheaves 20, to the correspondingradial arm on the opposite side. If desired a fifth horse may beemployed between the tongues, with any desired or suitable means forconnecting him with the chain 19, or other crossconnection, so that hispower will be utilized together with that of the outer horses, andequalized therewith. Any preferred devices or form of connection betweenthe opposite sides of the implement may be substituted for the chain 19,it not being the purpose of our present application or claims to coverany special form of cross-connection.

In operation it will be seen that when traction is applied to thedraft-bars 11 the power will be communicated, through equalizer-bars 13,to the fixed brackets 15, and that draw-bars 7 will be rotated, togetherwith radial arms 18, thus operating any suitable devices for connectionwith the opposite side of the implement, as hereinbefore indicated.

In the modification of our device shown in Fig. 2 the equalizer-bars 13are located above the draw-bars 7, upward extensions 21 of thedraft-bars 11 being provided, and the position of the brackets 15 beingchanged,

so as to support the equalizer-bars in elevated position. The operationin this form is practically the same as in that shown in Fig. 1.

Having described our invention, we claim as new and desire to secure byLetters Patent:

1. In an implement of the class described, in combination with a mainframe, a rotatable drawbar mounted in bearings carried by the frame,pendent draft-bars pivoted on said draw-bar, a" bracket secured to saiddraw-bar, an equalizing-bar pivoted centrally to said bracket,substantially parallel with said draw-bar, flexible connections betweensaid equalizing-bar and said draftbars, a rigid radial arm extendingfrom said draw-bar, and suitable connections between said radial arm andother operatlve parts of the implement.

2. In an implement of the class described,

In testimony whereof we affix our signatures in presence of twowitnesses.
